Mar-23-2019 | Initial version of CLI Guide with minimal command set | + +## Introduction +SONiC is an open source network operating system based on Linux that runs on switches from multiple vendors and ASICs. SONiC offers a full-suite of network functionality, like BGP and RDMA, that has been production-hardened in the data centers of some of the largest cloud-service providers. It offers teams the flexibility to create the network solutions they need while leveraging the collective strength of a large ecosystem and community. + +SONiC software shall be loaded in these [supported devices](https://github.com/Azure/SONiC/wiki/Supported-Devices-and-Platforms) and this CLI guide shall be used to configure the devices as well as to display the configuration, state and status. + +Follow the [Quick Start Guide](https://github.com/Azure/SONiC/wiki/Quick-Start) to boot the device in ONIE mode, install the SONiC software using the steps specified in the document and login to the device using the default username and password. + +After logging into the device, SONiC software can be configured in following three methods. + 1. Command Line Interface (CLI) + 2. [config_db.json](https://github.com/Azure/SONiC/wiki/Configuration) + 3. [minigraph.xml](https://github.com/Azure/SONiC/wiki/Configuration-with-Minigraph-(~Sep-2017)) + +This document explains the first method and gives the complete list of commands that are supported in SONiC 201904 version (build#19). +All the configuration commands need root privileges to execute them. Note that show commands can be executed by all users without the root privileges. +Root privileges can be obtained either by using "sudo" keyword in front of all config commands, or by going to root prompt using "sudo -i". +Note that all commands are case sensitive. + +- Example: + ``` + admin@sonic:~$ sudo config aaa authentication login tacacs+ + + OR + + admin@sonic:~$ sudo -i + root@sonic:~# config aaa authentication login tacacs+ + ``` + +Note that the command list given in this document is just a subset of all possible configurations in SONiC. +Please follow config_db.json based configuration for the complete list of configuration options. + +**Scope of this Document** + +It is assumed that all configuration commands start with the keyword “config” as prefix. +Any other scripts/utilities/commands that need user configuration control are wrapped as sub-commands under the “config” command. +The direct scripts/utilities/commands (examples given below) that are not wrapped under the "config" command are not in the scope of this document. + 1. acl_loader – This script is already wrapped inside “config acl” command; i.e. any ACL configuration that user is allowed to do is already part of “config acl” command; users are not expected to use the acl_loader script directly and hence this document need not explain the “acl_loader” script. + 2. crm – this command is not explained in this document. + 3. sonic-clear, sfputil, etc., This document does not explain these scripts also. + +## Basic Tasks + +This section covers the basic configurations related to the following: + 1. [SSH login](#SSH-Login) + 2. [Configuring the Management Interface](#Configuring-Management-Interface) + +### SSH Login + +All SONiC devices support both the serial console based login and the SSH based login by default. +The default credential (if not modified at image build time) for login is `admin/YourPaSsWoRd`. +In case of SSH login, users can login to the management interface (eth0) IP address after configuring the same using serial console. +Refer the following section for configuring the IP address for management interface. + +- Example: + ``` + At Console: + Debian GNU/Linux 9 sonic ttyS1 + + sonic login: admin + Password: YourPaSsWoRd + + SSH from any remote server to sonic can be done by connecting to SONiC IP + user@debug:~$ ssh admin@sonic_ip_address(or SONIC DNS Name) + admin@sonic's password: + ``` + +By default, login takes the user to the default prompt from which all the show commands can be executed. + +Go Back To [Beginning of the document](#) or [Beginning of this section](#basic-tasks) + +### Show Management Interface + +Please check [show ip interfaces](#show-ip-interfaces) + +### Configuring Management Interface + +The management interface (eth0) in SONiC is configured (by default) to use DHCP client to get the IP address from the DHCP server. Connect the management interface to the same network in which your DHCP server is connected and get the IP address from DHCP server. +The IP address received from DHCP server can be verified using the `/sbin/ifconfig eth0` Linux command. + +SONiC provides a CLI to configure the static IP for the management interface. There are few ways by which a static IP address can be configured for the management interface. + 1. Use the `config interface ip add eth0` command. + - Example: + ``` + admin@sonic:~$ sudo config interface ip add eth0 20.11.12.13/24 20.11.12.254 + ``` + 2. Use config_db.json and configure the MGMT_INTERFACE key with the appropriate values. Refer [here](https://github.com/Azure/SONiC/wiki/Configuration#Management-Interface) + 3. Use minigraph.xml and configure "ManagementIPInterfaces" tag inside "DpgDesc" tag as given at the [page](https://github.com/Azure/SONiC/wiki/Configuration-with-Minigraph-(~Sep-2017)) + +Once the IP address is configured, the same can be verified using either `show management_interface address` command or the `/sbin/ifconfig eth0` linux command. +Users can SSH login to this management interface IP address from their management network. + +- Example: + ``` + admin@sonic:~$ /sbin/ifconfig eth0 + eth0: flags=4163 mtu 1500 + inet 10.11.11.13 netmask 255.255.255.0 broadcast 10.11.12.255 + ``` +Go Back To [Beginning of the document](#) or [Beginning of this section](#basic-tasks) + +## Getting Help + +Subsections: + 1.

based configuration options for the AAA module. The list of commands/sub-commands possible for aaa is given below. + + Command: aaa authentication + sub-commands: + - aaa authentication failthrough + - aaa authentication fallback + - aaa authentication login + +**aaa authentication failthrough** + +This command is used to either enable or disable the failthrough option. +This command is useful when user has configured more than one tacacs+ server and when user has enabled tacacs+ authentication. +When authentication request to the first server fails, this configuration allows to continue the request to the next server. +When this configuration is enabled, authentication process continues through all servers configured. +When this is disabled and if the authentication request fails on first server, authentication process will stop and the login will be disallowed. + + +- Usage: + ``` + config aaa authentication failthrough (enable | disable | default) + ``` + + - Parameters: + - enable: This allows the AAA module to process with local authentication if remote authentication fails. + - disable: This disallows the AAA module to proceed further if remote authentication fails. + - default: This re-configures the default value, which is "enable". + + +- Example: + ``` + admin@sonic:~$ sudo config aaa authentication failthrough enable + ``` +**aaa authentication fallback** + +The command is not used at the moment. +When the tacacs+ authentication fails, it falls back to local authentication by default. + +- Usage: + ``` + config aaa authentication fallback (enable | disable | default) + ``` + +- Example: + ``` + admin@sonic:~$ sudo config aaa authentication fallback enable + ``` + +**aaa authentication login** + +This command is used to either configure whether AAA should use local database or remote tacacs+ database for user authentication. +By default, AAA uses local database for authentication. New users can be added/deleted using the linux commands (Note that the configuration done using linux commands are not preserved during reboot). +Admin can enable remote tacacs+ server based authentication by selecting the AUTH_PROTOCOL as tacacs+ in this command. +Admins need to configure the tacacs+ server accordingly and ensure that the connectivity to tacacas+ server is available via the management interface. +Once if the admins choose the remote authentication based on tacacs+ server, all user logins will be authenticated by the tacacs+ server. +If the authentication fails, AAA will check the "failthrough" configuration and authenticates the user based on local database if failthrough is enabled. + +- Usage: + ``` + config aaa authentication (tacacs+ | local | default) + ``` + + - Parameters: + - tacacs+: Enables remote authentication based on tacacs+ + - local: Disables remote authentication and uses local authentication + - default: Reset back to default value, which is only "local" authentication + + +- Example: + ``` + admin@sonic:~$ sudo config aaa authentication login tacacs+ + ``` + +Go Back To [Beginning of the document](#) or [Beginning of this section](#aaa--tacacs) + +### TACACS+ + +#### TACACS+ show commands + +**show tacacs** + +This command displays the global configuration fields and the list of all tacacs servers and their correponding configurations. + +- Usage: + ``` + show tacacs + ``` + +- Example: + ``` + admin@sonic:~$ show tacacs + TACPLUS global auth_type pap (default) + TACPLUS global timeout 99 + TACPLUS global passkey (default) + + TACPLUS_SERVER address 10.11.12.14 + priority 9 + tcp_port 50 + auth_type mschap + timeout 10 + passkey testing789 + + TACPLUS_SERVER address 10.0.0.9 + priority 1 + tcp_port 49 + ``` + +#### TACACS+ config commands + +This sub-section explains the command "config tacacs" and its sub-commands that are used to configure the following tacacs+ parameters. +Some of the parameters like authtype, passkey and timeout can be either configured at per server level or at global level (global value will be applied if there no server level configuration) + +1) Add/Delete the tacacs+ server details. +2) authtype - global configuration that is applied to all servers if there is no server specific configuration. +3) default - reset the authtype or passkey or timeout to the default values. +4) passkey - global configuration that is applied to all servers if there is no server specific configuration. +5) timeout - global configuration that is applied to all servers if there is no server specific configuration. + +**config tacacs add** + +This command is used to add a TACACS+ server to the tacacs server list. +Note that more than one tacacs+ (maximum of seven) can be added in the device. +When user tries to login, tacacs client shall contact the servers one by one. +When any server times out, device will try the next server one by one based on the priority value configured for that server. +When this command is executed, the configured tacacs+ server addresses are updated in /etc/pam.d/common-auth-sonic configuration file which is being used by tacacs service. + +- Usage: + ``` + config tacacs add [-t|--timeout ] [-k|--key ] [-a|--type ] [-o|--port ] [-p|--pri ] [-m|--use-mgmt-vrf] + ``` + + -

If a table_name is provided, the operation will be restricted in the specified table. All existing rules in the specified table or all tables will be removed. New rules loaded from file will be installed. If the table_name is specified, only rules within that table will be removed and new rules in that table will be installed. If the table_name is not specified, all rules from all tables will be removed and only the rules present in the input file will be added. + +The command does not modify anything in the list of acl tables. It modifies only the rules present in those pre-existing tables. + +In order to create acl tables, either follow the config_db.json method or minigraph method to populate the list of ACL tables. + +After creating tables, either the config_db.json method or the minigraph method or the CLI method (explained here) can be used to populate the rules in those ACL tables. + +This command updates only the ACL rules and it does not disturb the ACL tables; i.e. the output of "show acl table" is not alterted by using this command; only the output of "show acl rule" will be changed after this command. + +When "--session_name" optional argument is specified, command sets the session_name for the ACL table with this mirror session name.

Otherwise, it will use the default `/etc/sonic/config_db.json` file as the input file) into CONFIG_DB. +The configuration present in the input file is applied on top of the already running configuration. +This command does not flush the config DB before loading the new configuration (i.e., If the configuration present in the input file is same as the current running configuration, nothing happens) +If the config present in the input file is not present in running configuration, it will be added. +If the config present in the input file differs (when key matches) from that of the running configuration, it will be modified as per the new values for those keys. + +When user specifies the optional argument "-y" or "--yes", this command forces the loading without prompting the user for confirmation. +If the argument is not specified, it prompts the user to confirm whether user really wants to load this configuration file. + +- Usage: + ``` + config load [-y|--yes] [] + ``` + +- Example: + ``` + admin@sonic:~$ sudo config load + Load config from the file /etc/sonic/config_db.json? [y/N]: y + Running command: /usr/local/bin/sonic-cfggen -j /etc/sonic/config_db.json --write-to-db + ``` + +### Loading configuration from minigraph (XML) file + +**config load_minigraph** + +This command is used to load the configuration from /etc/sonic/minigraph.xml. +When users do not want to use configuration from config_db.json, they can copy the minigraph.xml configuration file to the device and load it using this command. +This command restarts various services running in the device and it takes some time to complete the command. + +NOTE: If the user had logged in using SSH, users might get disconnected and some configuration failures might happen which might be hard to recover. Users need to reconnect their SSH sessions after configuring the management IP address. It is recommended to execute this command from console port +NOTE: Management interface IP address and default route (or specific route) may require reconfiguration in case if those parameters are not part of the minigraph.xml. + +When user specifies the optional argument "-y" or "--yes", this command forces the loading without prompting the user for confirmation. +If the argument is not specified, it prompts the user to confirm whether user really wants to load this configuration file. + +When user specifies the optional argument "-n" or "--no-service-restart", this command loads the configuration without restarting dependent services +running on the device. One use case for this option is during boot time when config-setup service loads minigraph configuration and there is no services +running on the device. + +When user specifies the optional argument "-t" or "--traffic-shift-away", this command executes TSA command at the end to ensure the device remains in maintenance after loading minigraph. + +- Usage: + ``` + config load_minigraph [-y|--yes] [-n|--no-service-restart] [-t|--traffic-shift-away] + ``` + +- Example: + ``` + admin@sonic:~$ sudo config load_minigraph + Reload config from minigraph? [y/N]: y + Running command: /usr/local/bin/sonic-cfggen -j /etc/sonic/config_db.json --write-to-db + ``` + +### Reloading Configuration + +**config reload** + +This command is used to clear current configuration and import new configurationn from the input file or from /etc/sonic/config_db.json. +This command shall stop all services before clearing the configuration and it then restarts those services. + +This command restarts various services running in the device and it takes some time to complete the command. +NOTE: If the user had logged in using SSH, users **might get disconnected** depending upon the new management IP address. Users need to reconnect their SSH sessions. +In general, it is recommended to execute this command from console port after disconnecting all SSH sessions to the device. +When users to do “config reload” the newly loaded config may have management IP address, or it may not have management IP address. +If mgmtIP is there in the newly loaded config file, that mgmtIP might be same as previously configured value or it might be different. +This difference in mgmtIP address values results in following possible behaviours. + +Case1: Previously configured mgmtIP is same as newly loaded mgmtIP. The SSH session may not be affected at all, but it’s possible that there will be a brief interruption in the SSH session. But, assuming the client’s timeout value isn’t on the order of a couple of seconds, the session would most likely just resume again as soon as the interface is reconfigured and up with the same IP. +Case2: Previously configured mgmtIP is different from newly loaded mgmtIP. Users will lose their SSH connections. +Case3: Newly loaded config does not have any mgmtIP. Users will lose their SSH connections. + +NOTE: Management interface IP address and default route (or specific route) may require reconfiguration in case if those parameters are not part of the minigraph.xml. + +When user specifies the optional argument "-y" or "--yes", this command forces the loading without prompting the user for confirmation. +If the argument is not specified, it prompts the user to confirm whether user really wants to load this configuration file. + +When user specifies the optional argument "-n" or "--no-service-restart", this command clear and loads the configuration without restarting dependent services +running on the device. One use case for this option is during boot time when config-setup service loads existing old configuration and there is no services +running on the device. + +When user specifies the optional argument "-f" or "--force", this command ignores the system sanity checks. By default a list of sanity checks are performed and if one of the checks fail, the command will not execute. The sanity checks include ensuring the system status is not starting, all the essential services are up and swss is in ready state. + +- Usage: + ``` + config reload [-y|--yes] [-l|--load-sysinfo] [] [-n|--no-service-restart] [-f|--force] + ``` + +- Example: + ``` + admin@sonic:~$ sudo config reload + Clear current config and reload config from the file /etc/sonic/config_db.json?

Retry later or use -f to avoid system checks + ``` + ``` + admin@sonic:~$ sudo config reload -y + Relevant services are not up. Retry later or use -f to avoid system checks + ``` + ``` + admin@sonic:~$ sudo config reload -y + SwSS container is not ready. Retry later or use -f to avoid system checks + ``` + + +### Loading Management Configuration + +**config load_mgmt_config** + +This command is used to reconfigure hostname and mgmt interface based on device description file. +This command either uses the optional file specified as arguement or looks for the file "/etc/sonic/device_desc.xml". +If the file does not exist or if the file does not have valid fields for "hostname" and "ManagementAddress" (or "ManagementAddressV6"), it fails. + +When user specifies the optional argument "-y" or "--yes", this command forces the loading without prompting the user for confirmation. +If the argument is not specified, it prompts the user to confirm whether user really wants to load this configuration file. + +- Usage: + ``` + config load_mgmt_config [-y|--yes] [] + ``` + +- Example: + ``` + admin@sonic:~$ sudo config load_mgmt_config + Reload config from minigraph? [y/N]: y + Running command: /usr/local/bin/sonic-cfggen -M /etc/sonic/device_desc.xml --write-to-db + ``` + + +### Saving Configuration to a File for Persistence + +**config save** + +This command is to save the config DB configuration into the user-specified filename or into the default /etc/sonic/config_db.json. This saves the configuration into the disk which is available even after reboots. +Saved file can be transferred to remote machines for debugging.

If agent-id is not specified (with this CLI), an appropriate IP that belongs to the switch is used as the agent-id based on some simple heuristics. + +- Usage: + ``` + config sflow agent-id + ``` + + - Parameters: + - interface-name: specify the interface name whose ipv4 or ipv6 address will be used as the agent-id in sFlow datagrams. + +- Example: + ``` + admin@sonic:~# sudo config sflow agent-id add lo + ``` + +**config sflow** + +Globally, sFlow is disabled by default. When sFlow is enabled globally, the sflow deamon is started and sampling will start on all interfaces which have sFlow enabled at the interface level (see “config sflow interface…”). When sflow is disabled globally, sampling is stopped on all relevant interfaces and sflow daemon is stopped. + +- Usage: + ``` + config sflow + ``` +- Example: + ``` + admin@sonic:~# sudo config sflow enable + ``` +**config sflow interface** + +Enable/disable sflow at an interface level. By default, sflow is enabled on all interfaces at the interface level. Use this command to explicitly disable sFlow for a specific interface. An interface is sampled if sflow is enabled globally as well as at the interface level. Note that this configuration deals only with sFlow flow samples and not counter samples. + +- Usage: + ``` + config sflow interface + ``` + + - Parameters: + - interface-name: specify the interface for which sFlow flow samples have to be enabled/disabled. The “all” keyword is used as a convenience to enable/disable sflow at the interface level for all the interfaces. + +- Example: + ``` + admin@sonic:~# sudo config sflow interface disable Ethernet40 + ``` + +**config sflow interface sample-rate** + +Configure the sample-rate for a specific interface. + +The default sample rate for any interface is (ifSpeed / 1e6) where ifSpeed is in bits/sec.

This CLI is to be used only in case of exceptions (e.g., to set the sample-rate to the nearest power-of-2 if there are hardware restrictions in using the defaults) + +- Usage: + ``` + config sflow interface sample-rate + ``` + + - Parameters: + - interface-name: specify the interface for which the sampling rate value is to be set + - value: value is the average number of packets skipped before the sample is taken. "The sampling rate specifies random sampling probability as the ratio of packets observed to samples generated. For example a sampling rate of 256 specifies that, on average, 1 sample will be generated for every 256 packets observed."

This feature is currently supported by following dockers: BGP, teamD, and SWSS. A user can manage to restart a particular docker, with no interruption on packet forwarding and no effect on other services. This helps to reduce operational costs as well as development efforts. For example, to fix a bug in BGP routing stack, only the BGP docker image needs to be built, tested and upgraded. + +To achieve uninterrupted packet forwarding during the restarting stage and database reconciliation at the post restarting stage, warm restart enabled dockers with adjacency state machine facilitate standardized protocols. For example, a BGP restarting switch must have BGP "Graceful Restart" enabled, and its BGP neighbors must be "Graceful Restart Helper Capable", as specified in [IETF RFC4724](https://tools.ietf.org/html/rfc4724). + +Before warm restart BGP docker, the following BGP commands should be enabled: + ``` + bgp graceful-restart + bgp graceful-restart preserve-fw-state + ``` +In current SONiC release, the above two commands are enabled by default. + +It should be aware that during a warm restart, certain BGP fast convergence feature and black hole avoidance feature should either be disabled or be set to a lower preference to avoid conflicts with BGP graceful restart. + +For example, BGP BFD could be disabled via: + + ``` + no neighbor bfd + ``` + +otherwise, the fast failure detection would cause packet drop during warm reboot. + +Another commonly deployed blackhole avoidance feature: dynamic route priority adjustment, could be disabled via: + + ``` + no bgp max-med on-peerup + ``` + +to avoid large routes churn during BGP restart. + + +### Warm Restart show commands + +**show warm_restart config** + +This command displays all the configuration related to warm_restart. + +- Usage: + ``` + show warm_restart config + ``` + +- Example: + ``` + admin@sonic:~$ show warm_restart config + name enable timer_name timer_duration + ------ -------- ---------------- ---------------- + bgp true bgp_timer 100 + teamd false teamsyncd_timer 300 + swss false neighsyncd_timer 200 + system true NULL NULL + ``` + +**show warm_restart state** + +This command displays the warm_restart state. + +- Usage: + ``` + show warm_restart state + ``` + +- Example: + ``` + admin@sonic:~$ show warm_restart state + name restore_count state + ---------- --------------- ---------- + orchagent 0 + vlanmgrd 0 + bgp 1 reconciled + portsyncd 0 + teammgrd 1 + neighsyncd 0 + teamsyncd 1 + syncd 0 + natsyncd 0 + ``` + +Go Back To [Beginning of the document](#) or [Beginning of this section](#warm-restart) + +### Warm Restart Config commands + +This sub-section explains the various configuration related to warm restart feature.

-## Introduction -SONiC is an open source network operating system based on Linux that runs on switches from multiple vendors and ASICs. SONiC offers a full-suite of network functionality, like BGP and RDMA, that has been production-hardened in the data centers of some of the largest cloud-service providers. It offers teams the flexibility to create the network solutions they need while leveraging the collective strength of a large ecosystem and community. - -SONiC software shall be loaded in these [supported devices](https://github.com/Azure/SONiC/wiki/Supported-Devices-and-Platforms) and this CLI guide shall be used to configure the devices as well as to display the configuration, state and status. - -Follow the [Quick Start Guide](https://github.com/Azure/SONiC/wiki/Quick-Start) to boot the device in ONIE mode, install the SONiC software using the steps specified in the document and login to the device using the default username and password. - -After logging into the device, SONiC software can be configured in following three methods. - 1. Command Line Interface (CLI) - 2. [config_db.json](https://github.com/Azure/SONiC/wiki/Configuration) - 3. [minigraph.xml](https://github.com/Azure/SONiC/wiki/Configuration-with-Minigraph-(~Sep-2017)) - -This document explains the first method and gives the complete list of commands that are supported in SONiC 201904 version (build#19). -All the configuration commands need root privileges to execute them. Note that show commands can be executed by all users without the root privileges. -Root privileges can be obtained either by using "sudo" keyword in front of all config commands, or by going to root prompt using "sudo -i". -Note that all commands are case sensitive. - -- Example: - ``` - admin@sonic:~$ sudo config aaa authentication login tacacs+ - - OR - - admin@sonic:~$ sudo -i - root@sonic:~# config aaa authentication login tacacs+ - ``` - -Note that the command list given in this document is just a subset of all possible configurations in SONiC. -Please follow config_db.json based configuration for the complete list of configuration options. - -**Scope of this Document** - -It is assumed that all configuration commands start with the keyword “config” as prefix. -Any other scripts/utilities/commands that need user configuration control are wrapped as sub-commands under the “config” command. -The direct scripts/utilities/commands (examples given below) that are not wrapped under the "config" command are not in the scope of this document. - 1. acl_loader – This script is already wrapped inside “config acl” command; i.e. any ACL configuration that user is allowed to do is already part of “config acl” command; users are not expected to use the acl_loader script directly and hence this document need not explain the “acl_loader” script. - 2. crm – this command is not explained in this document. - 3. sonic-clear, sfputil, etc., This document does not explain these scripts also. - -## Basic Tasks - -This section covers the basic configurations related to the following: - 1. [SSH login](#SSH-Login) - 2. [Configuring the Management Interface](#Configuring-Management-Interface) - -### SSH Login - -All SONiC devices support both the serial console based login and the SSH based login by default. -The default credential (if not modified at image build time) for login is `admin/YourPaSsWoRd`. -In case of SSH login, users can login to the management interface (eth0) IP address after configuring the same using serial console. -Refer the following section for configuring the IP address for management interface. - -- Example: - ``` - At Console: - Debian GNU/Linux 9 sonic ttyS1 - - sonic login: admin - Password: YourPaSsWoRd - - SSH from any remote server to sonic can be done by connecting to SONiC IP - user@debug:~$ ssh admin@sonic_ip_address(or SONIC DNS Name) - admin@sonic's password: - ``` - -By default, login takes the user to the default prompt from which all the show commands can be executed. - -Go Back To [Beginning of the document](#) or [Beginning of this section](#basic-tasks) - -### Show Management Interface - -Please check [show ip interfaces](#show-ip-interfaces) - -### Configuring Management Interface - -The management interface (eth0) in SONiC is configured (by default) to use DHCP client to get the IP address from the DHCP server. Connect the management interface to the same network in which your DHCP server is connected and get the IP address from DHCP server. -The IP address received from DHCP server can be verified using the `/sbin/ifconfig eth0` Linux command. - -SONiC provides a CLI to configure the static IP for the management interface. There are few ways by which a static IP address can be configured for the management interface. - 1. Use the `config interface ip add eth0` command. - - Example: - ``` - admin@sonic:~$ sudo config interface ip add eth0 20.11.12.13/24 20.11.12.254 - ``` - 2. Use config_db.json and configure the MGMT_INTERFACE key with the appropriate values. Refer [here](https://github.com/Azure/SONiC/wiki/Configuration#Management-Interface) - 3. Use minigraph.xml and configure "ManagementIPInterfaces" tag inside "DpgDesc" tag as given at the [page](https://github.com/Azure/SONiC/wiki/Configuration-with-Minigraph-(~Sep-2017)) - -Once the IP address is configured, the same can be verified using either `show management_interface address` command or the `/sbin/ifconfig eth0` linux command. -Users can SSH login to this management interface IP address from their management network. - -- Example: - ``` - admin@sonic:~$ /sbin/ifconfig eth0 - eth0: flags=4163 mtu 1500 - inet 10.11.11.13 netmask 255.255.255.0 broadcast 10.11.12.255 - ``` -Go Back To [Beginning of the document](#) or [Beginning of this section](#basic-tasks) - -## Getting Help - -Subsections: - 1.

-### AAA - -#### AAA show commands - -This command is used to view the Authentication, Authorization & Accounting settings that are configured in the network node. - -**show aaa** - -This command displays the AAA settings currently present in the network node - -- Usage: - ``` - show aaa - ``` - -- Example: - ``` - admin@sonic:~$ show aaa - AAA authentication login local (default) - AAA authentication failthrough True (default) - AAA authentication fallback True (default) - ``` - -#### AAA config commands - -This sub-section explains all the possible CLI based configuration options for the AAA module. The list of commands/sub-commands possible for aaa is given below. - - Command: aaa authentication - sub-commands: - - aaa authentication failthrough - - aaa authentication fallback - - aaa authentication login - -**aaa authentication failthrough** - -This command is used to either enable or disable the failthrough option. -This command is useful when user has configured more than one tacacs+ server and when user has enabled tacacs+ authentication. -When authentication request to the first server fails, this configuration allows to continue the request to the next server. -When this configuration is enabled, authentication process continues through all servers configured. -When this is disabled and if the authentication request fails on first server, authentication process will stop and the login will be disallowed. - - -- Usage: - ``` - config aaa authentication failthrough (enable | disable | default) - ``` - - - Parameters: - - enable: This allows the AAA module to process with local authentication if remote authentication fails. - - disable: This disallows the AAA module to proceed further if remote authentication fails. - - default: This re-configures the default value, which is "enable". - - -- Example: - ``` - admin@sonic:~$ sudo config aaa authentication failthrough enable - ``` -**aaa authentication fallback** - -The command is not used at the moment. -When the tacacs+ authentication fails, it falls back to local authentication by default. - -- Usage: - ``` - config aaa authentication fallback (enable | disable | default) - ``` - -- Example: - ``` - admin@sonic:~$ sudo config aaa authentication fallback enable - ``` - -**aaa authentication login** - -This command is used to either configure whether AAA should use local database or remote tacacs+ database for user authentication. -By default, AAA uses local database for authentication. New users can be added/deleted using the linux commands (Note that the configuration done using linux commands are not preserved during reboot). -Admin can enable remote tacacs+ server based authentication by selecting the AUTH_PROTOCOL as tacacs+ in this command. -Admins need to configure the tacacs+ server accordingly and ensure that the connectivity to tacacas+ server is available via the management interface. -Once if the admins choose the remote authentication based on tacacs+ server, all user logins will be authenticated by the tacacs+ server. -If the authentication fails, AAA will check the "failthrough" configuration and authenticates the user based on local database if failthrough is enabled. - -- Usage: - ``` - config aaa authentication (tacacs+ | local | default) - ``` - - - Parameters: - - tacacs+: Enables remote authentication based on tacacs+ - - local: Disables remote authentication and uses local authentication - - default: Reset back to default value, which is only "local" authentication - - -- Example: - ``` - admin@sonic:~$ sudo config aaa authentication login tacacs+ - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](#aaa--tacacs) -

-Users can choose to have a default permit rule or default deny rule. In case of default "deny all" rule, add the permitted rules on top of the deny rule. In case of the default "permit all" rule, users can add the deny rules on top of it. If users have not confgured any rule, SONiC allows all traffic (which is "permit all"). - -5) Match - The fields from the packet header that need to be matched against the same present in the incoming traffic. - -- Usage: - ``` - show acl rule [] [] - ``` - -- Example: - ``` - admin@sonic:~$ show acl rule - Table Rule Priority Action Match - -------- ------------ ---------- ------------------------- ---------------------------- - SNMP_ACL RULE_1 9999 ACCEPT IP_PROTOCOL: 17 - SRC_IP: 1.1.1.1/32 - SSH_ONLY RULE_2 9998 ACCEPT IP_PROTOCOL: 6 - SRC_IP: 1.1.1.1/32 - EVERFLOW RULE_3 9997 MIRROR INGRESS: everflow0 SRC_IP: 20.0.0.2/32 - EVERFLOW RULE_4 9996 MIRROR EGRESS : everflow1 L4_SRC_PORT: 4621 - DATAACL RULE_5 9995 REDIRECT: Ethernet8 IP_PROTOCOL: 126 - DATAACL RULE_6 9994 FORWARD L4_SRC_PORT: 179 - DATAACL RULE_7 9993 FORWARD L4_DST_PORT: 179 - SNMP_ACL DEFAULT_RULE 1 DROP ETHER_TYPE: 2048 - SSH_ONLY DEFAULT_RULE 1 DROP ETHER_TYPE: 2048 - ``` - - -### ACL config commands -This sub-section explains the list of configuration options available for ACL module. -Note that there is no direct command to add or delete or modify the ACL table and ACL rule. -Existing ACL tables and ACL rules can be updated by specifying the ACL rules in json file formats and configure those files using this CLI command. - -**config acl update full** - -This command is to update the rules in all the tables or in one specific table in full. If a table_name is provided, the operation will be restricted in the specified table. All existing rules in the specified table or all tables will be removed. New rules loaded from file will be installed. If the table_name is specified, only rules within that table will be removed and new rules in that table will be installed. If the table_name is not specified, all rules from all tables will be removed and only the rules present in the input file will be added. - -The command does not modify anything in the list of acl tables. It modifies only the rules present in those pre-existing tables. - -In order to create acl tables, either follow the config_db.json method or minigraph method to populate the list of ACL tables. - -After creating tables, either the config_db.json method or the minigraph method or the CLI method (explained here) can be used to populate the rules in those ACL tables. - -This command updates only the ACL rules and it does not disturb the ACL tables; i.e. the output of "show acl table" is not alterted by using this command; only the output of "show acl rule" will be changed after this command. - -When "--session_name" optional argument is specified, command sets the session_name for the ACL table with this mirror session name. It fails if the specified mirror session name does not exist. - -When "--mirror_stage" optional argument is specified, command sets the mirror action to ingress/egress based on this parameter. By default command sets ingress mirror action in case argument is not specified. - -When the optional argument "max_priority" is specified, each rule’s priority is calculated by subtracting its “sequence_id” value from the “max_priority”. If this value is not passed, the default “max_priority” 10000 is used. - -- Usage: - ``` - config acl update full [--table_name ] [--session_name ] [--mirror_stage (ingress | egress)] [--max_priority ] - ``` - - - Parameters: - - table_name: Specifiy the name of the ACL table to load. Example: config acl update full "--table_name DT_ACL_T1 /etc/sonic/acl_table_1.json" - - session_name: Specifiy the name of the ACL session to load. Example: config acl update full "--session_name mirror_ses1 /etc/sonic/acl_table_1.json" - - priority_value: Specify the maximum priority to use when loading ACL rules. Example: config acl update full "--max-priority 100 /etc/sonic/acl_table_1.json" - - *NOTE 1: All these optional parameters should be inside double quotes. If none of the options are provided, double quotes are not required for specifying filename alone.* - *NOTE 2: Any number of optional parameters can be configured in the same command.* - -- Examples: - ``` - admin@sonic:~$ sudo config acl update full /etc/sonic/acl_full_snmp_1_2_ssh_4.json - admin@sonic:~$ sudo config acl update full "--table_name SNMP-ACL /etc/sonic/acl_full_snmp_1_2_ssh_4.json" - admin@sonic:~$ sudo config acl update full "--session_name everflow0 /etc/sonic/acl_full_snmp_1_2_ssh_4.json" - ``` - - This command will remove all rules from all the ACL tables and insert all the rules present in this input file. - Refer the example file [acl_full_snmp_1_2_ssh_4.json](#) that adds two rules for SNMP (Rule1 and Rule2) and one rule for SSH (Rule4) - Refer an example for input file format [here](https://github.com/Azure/sonic-mgmt/blob/master/ansible/roles/test/files/helpers/config_service_acls.sh) - Refer another example [here](https://github.com/Azure/sonic-mgmt/blob/master/ansible/roles/test/tasks/acl/acltb_test_rules_part_1.json) - -**config acl update incremental** - -This command is used to perform incremental update of ACL rule table. This command gets existing rules from Config DB and compares with rules specified in input file and performs corresponding modifications. - -With respect to DATA ACLs, the command does not assume that new dataplane ACLs can be inserted in betweeen by shifting existing ACLs in all ASICs. Therefore, this command performs a full update on dataplane ACLs. -With respect to control plane ACLs, this command performs an incremental update. -If we assume that "file1.json" is the already loaded ACL rules file and if "file2.json" is the input file that is passed as parameter for this command, the following requirements are valid for the input file. -1) First copy the file1.json to file2.json. -2) Remove the unwanted ACL rules from file2.json -3) Add the newly required ACL rules into file2.json. -4) Modify the existing ACL rules (that require changes) in file2.json. - -NOTE: If any ACL rule that is already available in file1.json is required even after this command execution, such rules should remain unalterted in file2.json. Don't remove them. -Note that "incremental" is working like "full". - -When "--session_name" optional argument is specified, command sets the session_name for the ACL table with this mirror session name. It fails if the specified mirror session name does not exist. - -When "--mirror_stage" optional argument is specified, command sets the mirror action to ingress/egress based on this parameter. By default command sets ingress mirror action in case argument is not specified. - -When the optional argument "max_priority" is specified, each rule’s priority is calculated by subtracting its “sequence_id” value from the “max_priority”. If this value is not passed, the default “max_priority” 10000 is used. - -- Usage: - ``` - config acl update incremental [--session_name ] [--mirror_stage (ingress | egress)] [--max_priority ] - ``` - - - Parameters: - - table_name: Specifiy the name of the ACL table to load.

This is done on a per-user basis. - -- Usage: - ``` - sonic-clear dropcounters - ``` - -- Example: - ``` - admin@sonic:~$ sonic-clear dropcounters - Cleared drop counters - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](##drop-counters) - -## Dynamic Buffer Management - -This section explains all the show and configuration commands regarding the dynamic buffer management. - -Dynamic buffer management is responsible for calculating buffer size according to the ports' configured speed and administrative state. In order to enable dynamic buffer management feature, the ports' speed must be configured. For this please refer [Interface naming mode config commands](#interface-naming-mode-config-commands) - -### Configuration commands - -**configure shared headroom pool** - -This command is used to configure the shared headroom pool. The shared headroom pool can be enabled in the following ways: - -- Configure the over subscribe ratio. In this case, the size of shared headroom pool is calculated as the accumulative xoff of all of the lossless PG divided by the over subscribe ratio. -- Configure the size. - -In case both of the above parameters have been configured, the `size` will take effect. To disable shared headroom pool, configure both parameters to zero. - -- Usage: - - ``` - config buffer shared-headroom-pool over-subscribe-ratio - config buffer shared-headroom-pool size - ``` - - The range of over-subscribe-ratio is from 1 to number of ports inclusive. - -- Example: - - ``` - admin@sonic:~$ sudo config shared-headroom-pool over-subscribe-ratio 2 - admin@sonic:~$ sudo config shared-headroom-pool size 1024000 - ``` - -**configure a lossless buffer profile** - -This command is used to configure a lossless buffer profile. - -- Usage: - - ``` - config buffer profile add --xon --xoff [-size ] [-dynamic_th ] [-pool ] - config buffer profile set --xon --xoff [-size ] [-dynamic_th ] [-pool ] - config buffer profile remove - ``` - - All the parameters are devided to two groups, one for headroom and one for dynamic_th. For any command at lease one group of parameters should be provided. - For headroom parameters: - - - `xon` is madantory. - - If shared headroom pool is disabled: - - At lease one of `xoff` and `size` should be provided and the other will be optional and conducted via the formula `xon + xoff = size`. - - `xon` + `xoff` <= `size`; For Mellanox platform xon + xoff == size - - If shared headroom pool is enabled: - - `xoff` should be provided. - - `size` = `xoff` if it is not provided. - - If only headroom parameters are provided, the `dynamic_th` will be taken from `CONFIG_DB.DEFAULT_LOSSLESS_BUFFER_PARAMETER.default_dynamic_th`. - - If only dynamic_th parameter is provided, the `headroom_type` will be set as `dynamic` and `xon`, `xoff` and `size` won't be set. This is only used for non default dynamic_th. In this case, the profile won't be deployed to ASIC directly. It can be configured to a lossless PG and then a dynamic profile will be generated based on the port's speed, cable length, and MTU and deployed to the ASIC. - - The subcommand `add` is designed for adding a new buffer profile to the system. - - The subcommand `set` is designed for modifying an existing buffer profile in the system. - For a profile with dynamically calculated headroom information, only `dynamic_th` can be modified. - - The subcommand `remove` is designed for removing an existing buffer profile from the system. When removing a profile, it shouldn't be referenced by any entry in `CONFIG_DB.BUFFER_PG`. - -- Example: - - ``` - admin@sonic:~$ sudo config buffer profile add profile1 --xon 18432 --xoff 18432 - admin@sonic:~$ sudo config buffer profile remove profile1 - ``` - -**config interface cable_length** - -This command is used to configure the length of the cable connected to a port. The cable_length is in unit of meters and must be suffixed with "m". - -- Usage: - - ``` - config interface cable_length - ``` - -- Example: - - ``` - admin@sonic:~$ sudo config interface cable_length Ethernet0 40m - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](#dynamic-buffer-management) - -**config interface buffer priority-group lossless** - -This command is used to configure the priority groups on which lossless traffic runs. - -- Usage: - - ``` - config interface buffer priority-group lossless add [profile] - config interface buffer priority-group lossless set [profile] - config interface buffer priority-group lossless remove [] - ``` - - The can be in one of the following two forms: - - - For a range of priorities, the lower bound and upper bound connected by a dash, like `3-4` - - For a single priority, the number, like `6` - - The `pg-map` represents the map of priorities for lossless traffic. It should be a string and in form of a bit map like `3-4`. The `-` connects the lower bound and upper bound of a range of priorities. - - The subcommand `add` is designed for adding a new lossless PG on top of current PGs. The new PG range must be disjoint with all existing PGs. - - For example, currently the PG range 3-4 exist on port Ethernet4, to add PG range 4-5 will fail because it isn't disjoint with 3-4. To add PG range 5-6 will succeed. After that both range 3-4 and 5-6 will work as lossless PG. - - The `override-profile` parameter is optional. When provided, it represents the predefined buffer profile for headroom override. - - The subcommand `set` is designed for modifying an existing PG from dynamic calculation to headroom override or vice versa. The `pg-map` must be an existing PG. - - The subcommand `remove` is designed for removing an existing PG. The option `pg-map` must be an existing PG. All lossless PGs will be removed in case no `pg-map` provided. - -- Example: - - To configure lossless_pg on a port: - - ``` - admin@sonic:~$ sudo config interface buffer priority-group lossless add Ethernet0 3-4 - ``` - - To change the profile used for lossless_pg on a port: - - ``` - admin@sonic:~$ sudo config interface buffer priority-group lossless set Ethernet0 3-4 new-profile - ``` - - To remove one lossless priority from a port: - - ``` - admin@sonic:~$ sudo config interface buffer priority-group lossless remove Ethernet0 6 - ``` - - To remove all lossless priorities from a port: - - ``` - admin@sonic:~$ sudo config interface buffer priority-group lossless remove Ethernet0 - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](#dynamic-buffer-management) - -**config interface buffer queue** - -This command is used to configure the buffer profiles for queues. - -- Usage: - - ``` - config interface buffer queue add - config interface buffer queue set - config interface buffer queue remove - ``` - - The represents the map of queues. It can be in one of the following two forms: - - - For a range of priorities, the lower bound and upper bound connected by a dash, like `3-4` - - For a single priority, the number, like `6` - - The subcommand `add` is designed for adding a buffer profile for a group of queues. The new queue range must be disjoint with all queues with buffer profile configured. - - For example, currently the buffer profile configured on queue 3-4 on port Ethernet4, to configure buffer profile on queue 4-5 will fail because it isn't disjoint with 3-4. To configure it on range 5-6 will succeed. - - The `profile` parameter represents a predefined egress buffer profile to be configured on the queues. - - The subcommand `set` is designed for modifying an existing group of queues. - - The subcommand `remove` is designed for removing buffer profile on an existing group of queues. - -- Example: - - To configure buffer profiles for queues on a port: - - ``` - admin@sonic:~$ sudo config interface buffer queue add Ethernet0 3-4 egress_lossless_profile - ``` - - To change the profile used for queues on a port: - - ``` - admin@sonic:~$ sudo config interface buffer queue set Ethernet0 3-4 new-profile - ``` - - To remove a group of queues from a port: -

Otherwise, it will use the default `/etc/sonic/config_db.json` file as the input file) into CONFIG_DB. -The configuration present in the input file is applied on top of the already running configuration. -This command does not flush the config DB before loading the new configuration (i.e., If the configuration present in the input file is same as the current running configuration, nothing happens) -If the config present in the input file is not present in running configuration, it will be added. -If the config present in the input file differs (when key matches) from that of the running configuration, it will be modified as per the new values for those keys. - -When user specifies the optional argument "-y" or "--yes", this command forces the loading without prompting the user for confirmation. -If the argument is not specified, it prompts the user to confirm whether user really wants to load this configuration file. - -- Usage: - ``` - config load [-y|--yes] [] - ``` - -- Example: - ``` - admin@sonic:~$ sudo config load - Load config from the file /etc/sonic/config_db.json? [y/N]: y - Running command: /usr/local/bin/sonic-cfggen -j /etc/sonic/config_db.json --write-to-db - ``` - -### Loading configuration from minigraph (XML) file - -**config load_minigraph** - -This command is used to load the configuration from /etc/sonic/minigraph.xml. -When users do not want to use configuration from config_db.json, they can copy the minigraph.xml configuration file to the device and load it using this command. -This command restarts various services running in the device and it takes some time to complete the command. - -NOTE: If the user had logged in using SSH, users might get disconnected and some configuration failures might happen which might be hard to recover. Users need to reconnect their SSH sessions after configuring the management IP address. It is recommended to execute this command from console port -NOTE: Management interface IP address and default route (or specific route) may require reconfiguration in case if those parameters are not part of the minigraph.xml. - -When user specifies the optional argument "-y" or "--yes", this command forces the loading without prompting the user for confirmation. -If the argument is not specified, it prompts the user to confirm whether user really wants to load this configuration file. - -When user specifies the optional argument "-n" or "--no-service-restart", this command loads the configuration without restarting dependent services -running on the device. One use case for this option is during boot time when config-setup service loads minigraph configuration and there is no services -running on the device. - -When user specifies the optional argument "-t" or "--traffic-shift-away", this command executes TSA command at the end to ensure the device remains in maintenance after loading minigraph. - -- Usage: - ``` - config load_minigraph [-y|--yes] [-n|--no-service-restart] [-t|--traffic-shift-away] - ``` - -- Example: - ``` - admin@sonic:~$ sudo config load_minigraph - Reload config from minigraph?

Users need to reconnect their SSH sessions. -In general, it is recommended to execute this command from console port after disconnecting all SSH sessions to the device. -When users to do “config reload” the newly loaded config may have management IP address, or it may not have management IP address. -If mgmtIP is there in the newly loaded config file, that mgmtIP might be same as previously configured value or it might be different. -This difference in mgmtIP address values results in following possible behaviours. - -Case1: Previously configured mgmtIP is same as newly loaded mgmtIP. The SSH session may not be affected at all, but it’s possible that there will be a brief interruption in the SSH session. But, assuming the client’s timeout value isn’t on the order of a couple of seconds, the session would most likely just resume again as soon as the interface is reconfigured and up with the same IP. -Case2: Previously configured mgmtIP is different from newly loaded mgmtIP. Users will lose their SSH connections. -Case3: Newly loaded config does not have any mgmtIP. Users will lose their SSH connections. - -NOTE: Management interface IP address and default route (or specific route) may require reconfiguration in case if those parameters are not part of the minigraph.xml. - -When user specifies the optional argument "-y" or "--yes", this command forces the loading without prompting the user for confirmation. -If the argument is not specified, it prompts the user to confirm whether user really wants to load this configuration file. - -When user specifies the optional argument "-n" or "--no-service-restart", this command clear and loads the configuration without restarting dependent services -running on the device. One use case for this option is during boot time when config-setup service loads existing old configuration and there is no services -running on the device. - -When user specifies the optional argument "-f" or "--force", this command ignores the system sanity checks. By default a list of sanity checks are performed and if one of the checks fail, the command will not execute. The sanity checks include ensuring the system status is not starting, all the essential services are up and swss is in ready state. - -- Usage: - ``` - config reload [-y|--yes] [-l|--load-sysinfo] [] [-n|--no-service-restart] [-f|--force] - ``` - -- Example: - ``` - admin@sonic:~$ sudo config reload - Clear current config and reload config from the file /etc/sonic/config_db.json?

The sub-commands for "config platform" gets populated only on mellanox platforms. -There are no other subcommands on non-Mellanox devices and hence this command appears empty and useless in other platforms. -The platform mellanox command currently includes a single sub command which is the SDK sniffer. -The SDK sniffer is a troubleshooting tool which records the RPC calls from the Mellanox SDK user API library to the sx_sdk task into a .pcap file. -This .pcap file can be replayed afterward to get the exact same configuration state on SDK and FW to reproduce and investigate issues. - -A new folder will be created to store the sniffer files: "/var/log/mellanox/sniffer/". The result file will be stored in a .pcap file, which includes a time stamp of the starting time in the file name, for example, "sx_sdk_sniffer_20180224081306.pcap" -In order to have a complete .pcap file with all the RPC calls, the user should disable the SDK sniffer. Swss service will be restarted and no capturing is taken place from that moment. -It is recommended to review the .pcap file while sniffing is disabled. -Once SDK sniffer is enabled/disabled, the user is requested to approve that swss service will be restarted. -For example: To change SDK sniffer status, swss service will be restarted, continue? [y/N]: -In order to avoid that confirmation the -y / --yes option should be used. - -- Usage: - ``` - config platform mlnx sniffer sdk [-y|--yes] - ``` - -- Example: - ``` - admin@sonic:~$ config platform mlnx sniffer sdk - To change SDK sniffer status, swss service will be restarted, continue? [y/N]: y - NOTE: In order to avoid that confirmation the -y / --yes option should be used. - ``` - -### Barefoot Platform Specific Commands - -**show platform barefoot profile** - -This command displays active P4 profile and lists available ones. - -- Usage: - ``` - show platform barefoot profile - ``` - -- Example: - ``` - admin@sonic:~$ show platform barefoot profile - Current profile: x1 - Available profile(s): - x1 - x2 - ``` - -**config platform barefoot profile** - -This command sets P4 profile. - -- Usage: - ``` - config platform barefoot profile [-y|--yes] - ``` - -- Example: - ``` - admin@sonic:~$ sudo config platform barefoot profile x1 - Swss service will be restarted, continue? [y/N]: y - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](#platform-specific-commands) - - -## PortChannels - -### PortChannel Show commands - -**show interfaces portchannel** - -This command displays all the port channels that are configured in the device and its current status. - -- Usage: - ``` - show interfaces portchannel - ``` - -- Example: - ``` - admin@sonic:~$ show interfaces portchannel - Flags: A - active, I - inactive, Up - up, Dw - Down, N/A - not available, S - selected, D - deselected - No. Team Dev Protocol Ports - ----- ------------- ----------- --------------------------- - 24 PortChannel24 LACP(A)(Up) Ethernet28(S) Ethernet24(S) - 48 PortChannel48 LACP(A)(Up) Ethernet52(S) Ethernet48(S) - 40 PortChannel40 LACP(A)(Up) Ethernet44(S) Ethernet40(S) - 0 PortChannel0 LACP(A)(Up) Ethernet0(S) Ethernet4(S) - 8 PortChannel8 LACP(A)(Up) Ethernet8(S) Ethernet12(S) - ``` - - -### PortChannel Config commands - -This sub-section explains how to configure the portchannel and its member ports. - -**config portchannel** - -This command is used to add or delete the portchannel. -It is recommended to use portchannel names in the format "PortChannelxxxx", where "xxxx" is number of 1 to 4 digits. Ex: "PortChannel0002". - -NOTE: If users specify any other name like "pc99", command will succeed, but such names are not supported. Such names are not printed properly in the "show interface portchannel" command. It is recommended not to use such names. - -When any port is already member of any other portchannel and if user tries to add the same port in some other portchannel (without deleting it from the current portchannel), the command fails internally. But, it does not print any error message. In such cases, remove the member from current portchannel and then add it to new portchannel. - -Command takes two optional arguements given below. -1) min-links - minimum number of links required to bring up the portchannel -2) fallback - true/false. LACP fallback feature can be enabled / disabled. When it is set to true, only one member port will be selected as active per portchannel during fallback mode. Refer https://github.com/Azure/SONiC/blob/master/doc/lag/LACP%20Fallback%20Feature%20for%20SONiC_v0.5.md for more details about fallback feature. -3) fast-rate - true/false, default is flase (slow). Option specifying the rate in which we'll ask our link partner to transmit LACPDU packets in 802.3ad mode. slow - request partner to transmit LACPDUs every 30 seconds, fast - request partner to transmit LACPDUs every 1 second. In slow mode 60-90 seconds needed to detect linkdown, in fast mode only 2-3 seconds. - -A port channel can be deleted only if it does not have any members or the members are already deleted. When a user tries to delete a port channel and the port channel still has one or more members that exist, the deletion of port channel is blocked. - -- Usage: - ``` - config portchannel (add | del) [--min-links ] [--fallback (true | false)] [--fast-rate (true | false)] - ``` - -- Example (Create the portchannel with name "PortChannel0011"): - ``` - admin@sonic:~$ sudo config portchannel add PortChannel0011 - ``` - -**config portchannel member** - -This command adds or deletes a member port to/from the already created portchannel. - -- Usage: - ``` - config portchannel member (add | del) - ``` - -- Example (Add interface Ethernet4 as member of the portchannel "PortChannel0011"): - ``` - admin@sonic:~$ sudo config portchannel member add PortChannel0011 Ethernet4 -

In case if users wants to modify any of these configurations, they need to modify the appropriate QOS tables and fields in these files and then use this reload command. -This command uses those modified buffers.json.j2 file & qos.json.j2 file and reloads the new QOS configuration. -If users have not made any changes in these configuration files, this command need not be executed. - -Some of the example QOS configurations that users can modify are given below. -1) TC_TO_PRIORITY_GROUP_MAP -2) MAP_PFC_PRIORITY_TO_QUEUE -3) TC_TO_QUEUE_MAP -4) DSCP_TO_TC_MAP -5) MPLS_TC_TO_TC_MAP -6) SCHEDULER -7) PFC_PRIORITY_TO_PRIORITY_GROUP_MAP -8) PORT_QOS_MAP -9) WRED_PROFILE -10) CABLE_LENGTH -11) BUFFER_QUEUE - -- Usage: - ``` - config qos reload - ``` - -- Example: - ``` - admin@sonic:~$ sudo config qos reload - Running command: /usr/local/bin/sonic-cfggen -d -t /usr/share/sonic/device/x86_64-dell_z9100_c2538-r0/Force10-Z9100-C32/buffers.json.j2 >/tmp/buffers.json - Running command: /usr/local/bin/sonic-cfggen -d -t /usr/share/sonic/device/x86_64-dell_z9100_c2538-r0/Force10-Z9100-C32/qos.json.j2 -y /etc/sonic/sonic_version.yml >/tmp/qos.json - Running command: /usr/local/bin/sonic-cfggen -j /tmp/buffers.json --write-to-db - Running command: /usr/local/bin/sonic-cfggen -j /tmp/qos.json --write-to-db - - In this example, it uses the buffers.json.j2 file and qos.json.j2 file from platform specific folders. - When there are no changes in the platform specific configutation files, they internally use the file "/usr/share/sonic/templates/buffers_config.j2" and "/usr/share/sonic/templates/qos_config.j2" to generate the configuration. - ``` - -**config qos reload --ports port_list** - -This command is used to reload the default QoS configuration on a group of ports. -Typically, the default QoS configuration is in the following tables. -1) PORT_QOS_MAP -2) QUEUE -3) BUFFER_PG -4) BUFFER_QUEUE -5) BUFFER_PORT_INGRESS_PROFILE_LIST -6) BUFFER_PORT_EGRESS_PROFILE_LIST -7) CABLE_LENGTH - -If there was QoS configuration in the above tables for the ports: - - - if `--force` option is provied, the existing QoS configuration will be replaced by the default QoS configuration, - - otherwise, the command will exit with nothing updated. - -- Usage: - ``` - config qos reload --ports [,port] - ``` - -- Example: - ``` - admin@sonic:~$ sudo config qos reload --ports Ethernet0,Ethernet4 - - In this example, it updates the QoS configuration on port Ethernet0 and Ethernet4 to default. - If there was QoS configuration on the ports, the command will clear the existing QoS configuration on the port and reload to default. - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](#qos) - -## sFlow - -### sFlow Show commands - -**show sflow** - -This command displays the global sFlow configuration that includes the admin state, collectors, the Agent ID and counter polling interval. - -- Usage: - ``` - show sflow - ``` - -- Example: - ``` - admin@sonic:~# show sflow - sFlow Global Information: - sFlow Admin State: up - sFlow Polling Interval: default - sFlow AgentID: lo - - 2 Collectors configured: - Name: collector_A IP addr: 10.11.46.2 UDP port: 6343 - Name: collector_lo IP addr: 127.0.0.1 UDP port: 6343 - ``` - - -**show sflow interface** - -This command displays the per-interface sflow admin status and the sampling rate. - -- Usage: - ``` - show sflow interface - ``` - -- Example: - ``` - admin@sonic:~# show sflow interface - - sFlow interface configurations - +-------------+---------------+-----------------+ - | Interface | Admin State | Sampling Rate | - +=============+===============+=================+ - | Ethernet0 | up | 4000 | - +-------------+---------------+-----------------+ - | Ethernet1 | up | 4000 | - +-------------+---------------+-----------------+ - ... - +-------------+---------------+-----------------+ - | Ethernet61 | up | 4000 | - +-------------+---------------+-----------------+ - | Ethernet62 | up | 4000 | - +-------------+---------------+-----------------+ - | Ethernet63 | up | 4000 | - +-------------+---------------+-----------------+ - - ``` - -### sFlow Config commands - -**config sflow collector add** - -This command is used to add a sFlow collector. Note that a maximum of 2 collectors is allowed. - -- Usage: - ``` - config sflow collector add [port ] - ``` - - - Parameters: - - collector-name: unique name of the sFlow collector - - ipv4-address : IP address of the collector in dotted decimal format for IPv4 - - ipv6-address : x: x: x: x::x format for IPv6 address of the collector (where :: notation specifies successive hexadecimal fields of zeros) - - port (OPTIONAL): specifies the UDP port of the collector (the range is from 0 to 65535. The default is 6343.) - -- Example: - ``` - admin@sonic:~# sudo config sflow collector add collector_A 10.11.46.2 - ``` - -**config sflow collector del** - -This command is used to delete a sFlow collector with the given name. - -- Usage: - ``` - config sflow collector del - ``` - - - Parameters: - - collector-name: unique name of the sFlow collector - -- Example: - ``` - admin@sonic:~# sudo config sflow collector del collector_A - ``` - -**config sflow agent-id** - -This command is used to add/delete the sFlow agent-id. This setting is global (applicable to both collectors) and optional. Only a single agent-id is allowed. If agent-id is not specified (with this CLI), an appropriate IP that belongs to the switch is used as the agent-id based on some simple heuristics. - -- Usage: - ``` - config sflow agent-id - ``` - - - Parameters: - - interface-name: specify the interface name whose ipv4 or ipv6 address will be used as the agent-id in sFlow datagrams. - -- Example: - ``` - admin@sonic:~# sudo config sflow agent-id add lo - ``` - -**config sflow** - -Globally, sFlow is disabled by default. When sFlow is enabled globally, the sflow deamon is started and sampling will start on all interfaces which have sFlow enabled at the interface level (see “config sflow interface…”). When sflow is disabled globally, sampling is stopped on all relevant interfaces and sflow daemon is stopped. - -- Usage: - ``` - config sflow - ``` -- Example: - ``` - admin@sonic:~# sudo config sflow enable - ``` -**config sflow interface** - -Enable/disable sflow at an interface level. By default, sflow is enabled on all interfaces at the interface level. Use this command to explicitly disable sFlow for a specific interface. An interface is sampled if sflow is enabled globally as well as at the interface level. Note that this configuration deals only with sFlow flow samples and not counter samples. - -- Usage: - ``` - config sflow interface - ``` - - - Parameters: - - interface-name: specify the interface for which sFlow flow samples have to be enabled/disabled. The “all” keyword is used as a convenience to enable/disable sflow at the interface level for all the interfaces. - -- Example: - ``` - admin@sonic:~# sudo config sflow interface disable Ethernet40 - ``` - -**config sflow interface sample-rate** - -Configure the sample-rate for a specific interface. - -The default sample rate for any interface is (ifSpeed / 1e6) where ifSpeed is in bits/sec. So, the default sample rate based on interface speed is: - - 1-in-1000 for a 1G link - 1-in-10,000 for a 10G link - 1-in-40,000 for a 40G link - 1-in-50,000 for a 50G link - 1-in-100,000 for a 100G link - -It is recommended not to change the defaults. This CLI is to be used only in case of exceptions (e.g., to set the sample-rate to the nearest power-of-2 if there are hardware restrictions in using the defaults) - -- Usage: - ``` - config sflow interface sample-rate - ``` - - - Parameters: - - interface-name: specify the interface for which the sampling rate value is to be set - - value: value is the average number of packets skipped before the sample is taken. "The sampling rate specifies random sampling probability as the ratio of packets observed to samples generated. For example a sampling rate of 256 specifies that, on average, 1 sample will be generated for every 256 packets observed." Valid range 256:8388608. - -- Example: - ``` - admin@sonic:~# sudo config sflow interface sample-rate Ethernet32 1000 - ``` -**config sflow polling-interval** - -This command is used to set the counter polling interval. Default is 20 seconds. - -- Usage: - ``` - config sflow polling-interval - ``` - - - Parameters: - - value: 0-300 seconds.

This feature is currently supported by following dockers: BGP, teamD, and SWSS. A user can manage to restart a particular docker, with no interruption on packet forwarding and no effect on other services. This helps to reduce operational costs as well as development efforts. For example, to fix a bug in BGP routing stack, only the BGP docker image needs to be built, tested and upgraded. - -To achieve uninterrupted packet forwarding during the restarting stage and database reconciliation at the post restarting stage, warm restart enabled dockers with adjacency state machine facilitate standardized protocols. For example, a BGP restarting switch must have BGP "Graceful Restart" enabled, and its BGP neighbors must be "Graceful Restart Helper Capable", as specified in [IETF RFC4724](https://tools.ietf.org/html/rfc4724). - -Before warm restart BGP docker, the following BGP commands should be enabled: - ``` - bgp graceful-restart - bgp graceful-restart preserve-fw-state - ``` -In current SONiC release, the above two commands are enabled by default. - -It should be aware that during a warm restart, certain BGP fast convergence feature and black hole avoidance feature should either be disabled or be set to a lower preference to avoid conflicts with BGP graceful restart. - -For example, BGP BFD could be disabled via: - - ``` - no neighbor bfd - ``` - -otherwise, the fast failure detection would cause packet drop during warm reboot. - -Another commonly deployed blackhole avoidance feature: dynamic route priority adjustment, could be disabled via: - - ``` - no bgp max-med on-peerup - ``` - -to avoid large routes churn during BGP restart. - - -### Warm Restart show commands - -**show warm_restart config** - -This command displays all the configuration related to warm_restart. - -- Usage: - ``` - show warm_restart config - ``` - -- Example: - ``` - admin@sonic:~$ show warm_restart config - name enable timer_name timer_duration - ------ -------- ---------------- ---------------- - bgp true bgp_timer 100 - teamd false teamsyncd_timer 300 - swss false neighsyncd_timer 200 - system true NULL NULL - ``` - -**show warm_restart state** - -This command displays the warm_restart state. - -- Usage: - ``` - show warm_restart state - ``` - -- Example: - ``` - admin@sonic:~$ show warm_restart state - name restore_count state - ---------- --------------- ---------- - orchagent 0 - vlanmgrd 0 - bgp 1 reconciled - portsyncd 0 - teammgrd 1 - neighsyncd 0 - teamsyncd 1 - syncd 0 - natsyncd 0 - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](#warm-restart) - -### Warm Restart Config commands - -This sub-section explains the various configuration related to warm restart feature.

Note that it's *not* allowed to remove currently running image. - -- Usage: - ``` - sonic-installer remove [-y|--yes] - ``` - -- Example: - ``` - admin@sonic:~$ sudo sonic-installer remove SONiC-OS-HEAD.YYYY - Image will be removed, continue? [y/N]: y - Updating GRUB... - Done - Removing image root filesystem... - Done - Command: grub-set-default --boot-directory=/host 0 - - Image removed - ``` - -**sonic-installer cleanup** - -This command removes all unused images from the device, leaving only the currently active image and the image which will be booted into next (if different) installed. If there are no images which can be removed, the command will output `No image(s) to remove` - -- Usage: - ``` - sonic-installer cleanup [-y|--yes] - ``` - -- Example: - ``` - admin@sonic:~$ sudo sonic-installer cleanup - Remove images which are not current and next, continue? [y/N]: y - No image(s) to remove - ``` - -Go Back To [Beginning of the document](#) or [Beginning of this section](#software-installation-and-management) - - - -## Troubleshooting Commands - -For troubleshooting and debugging purposes, this command gathers pertinent information about the state of the device; information is as diverse as syslog entries, database state, routing-stack state, etc., It then compresses it into an archive file. This archive file can be sent to the SONiC development team for examination. -Resulting archive file is saved as `/var/dump/_YYYYMMDD_HHMMSS.tar.gz` - -- Usage: - ``` - show techsupport - ``` - -- Example: - ``` - admin@sonic:~$ show techsupport [--since=] - ``` - -If the SONiC system was running for quite some time `show techsupport` will produce a large dump file. To reduce the amount of syslog and core files gathered during system dump use `--since` option: - -- Examples: - ``` - admin@sonic:~$ show techsupport --since=yesterday # Will collect syslog and core files for the last 24 hours - ``` - ``` - admin@sonic:~$ show techsupport --since='hour ago' # Will collect syslog and core files for the last one hour - ``` - -### Debug Dumps - -In SONiC, there usually exists a set of tables related/relevant to a particular module. All of these might have to be looked at to confirm whether any configuration update is properly applied and propagated. This utility comes in handy because it prints a unified view of the redis-state for a given module - -- Usage: - ``` - Usage: dump state [OPTIONS] MODULE IDENTIFIER - Dump the redis-state of the identifier for the module specified - - Options: - -s, --show Display Modules Available - -d, --db TEXT Only dump from these Databases - -t, --table Print in tabular format [default: False] - -k, --key-map Only fetch the keys matched, don't extract field-value dumps [default: False] - -v, --verbose Prints any intermediate output to stdout useful for dev & troubleshooting [default: False] - -n, --namespace TEXT Dump the redis-state for this namespace. [default: DEFAULT_NAMESPACE] - --help Show this message and exit. - ``` - - -- Examples: - ``` - root@sonic# dump state --show - Module Identifier - -------- ------------ - port port_name - copp trap_id - ``` - - ``` - admin@sonic:~$ dump state copp arp_req --key-map --db ASIC_DB - { - "arp_req": { - "ASIC_DB": { - "keys": [ - "ASIC_STATE:SAI_OBJECT_TYPE_HOSTIF_TRAP:oid:0x22000000000c5b", - "ASIC_STATE:SAI_OBJECT_TYPE_HOSTIF_TRAP_GROUP:oid:0x11000000000c59", - "ASIC_STATE:SAI_OBJECT_TYPE_POLICER:oid:0x12000000000c5a", - "ASIC_STATE:SAI_OBJECT_TYPE_QUEUE:oid:0x15000000000626" - ], - "tables_not_found": [], - "vidtorid": { - "oid:0x22000000000c5b": "oid:0x200000000022", - "oid:0x11000000000c59": "oid:0x300000011", - "oid:0x12000000000c5a": "oid:0x200000012", - "oid:0x15000000000626": "oid:0x12e0000040015" - } - } - } - } - ``` - -### Event Driven Techsupport Invocation - -This feature/capability makes the techsupport invocation event-driven based on core dump generation.
